I Application led March 8, 1900. Serial No. 7,828. (No model.)

To all whom, t may concer-rt.'

Be it known that I, JAMES R. GEIEFETH, av

citizen of the United States, residing at Norwwalk,county of Fairfield, State of Connecticut,

have invented a new and useful Machine for' Trimming Curled Hat-Brims, of which the following is a specication.

My invention has for its object to provide a simple, durable, inexpensive, and easily- 1o adjusted and easily-operated machine for trimming the brilns of curled hats, this operation being sometimes known in the art as planing andsometimes as paring the brims.

With the above end in View I have devised the novel brim-trimming machine, of which the following description, in connection with the accompanying drawings, is a speciii-l cation, reference characters being used to des-` zo ignate the several parts.

Figure l is a side elevation of the machine complete; Fig. la, a detail sectional view corresponding therewith; Fig. 2, a plan View; Fig. 3, a similar view showing the position of the oscillating cutter-plate relatively to the b0dy of the rotating head when the cutter is acting upon one of the quarters of a hat-brim, the brim-plate being partly broken away and the standard in horizontal section; Fig. 4, an 3o enlarged sectional View on the line 4 4 in Fig.

2; Fig. 5, an enlarged plan view of the inner end of the carrying-slide, showing the yoke and rollers; Fig. 6, an elevation looking in the direction of the arrow in Fig. 3, one of 3g the brim-plates being in section on the line 6 6 in Fig. l; Fig. 7,'an enlarged plan view of the inner end of the cross-plate, the standardl being in section; and Fig. 8 is an enlarged sectional view on the -line 8 8 in Fig. 1.

A denotes a suitable base or bed plate which may be made of metal or wood and is adapted to be secured in place upon a bench or table in any suitable manner, as by screws passing through holes 20.

B denotes a standard extending upward from the bed, and C a cam-track resting upon legs 21, which-are rigidly secured to the base. The operative surface of this cam-track is a curved vplane lowest at the ends, highest at 5o the sides, and inclined at the quarters to corva rack 24.

'with the ordinary curvature of a hat-brim.

respond substantially to the plane of an ordinary vhat-brim.

The hat-body to be operated upon is held in place by an internal expander D, which may be of any ordinary or preferred construction and is shown as operated by an oscillatory rod 22 in the standard, provided at its lower end with a hand-lever 23, adapted to engage Just below the expander and rigidly securedfto the standard is a brim-plate 6o E, which is convex from end to end-that is to say, the brim-plate is lowest at the ends, highest at the sides, and inclined at the quarters in order to correspond substantially 25 denotes side plates which support the upward curves at the sides of the brim. These side plates are made adjustable to provide .for dierent sizes of hats in any simple and convenient manner. In the present in- 7o stance I have shown the side plates as carrying eyes 26, whose shanks 27 extend through slots 28 in the brim-plate and engage, respectively, the right and left threads of a screw F, which is carried by lugs 29, extending from the brim-plate. This screw is free to turn in the lugs, but is held against lateral movement therein, and a finger-piece 30 is provided at one end for convenience in Operating it.

G denotes a cam-plate detachably secured to a cam-plate holder Hin any suitable manner, as by thumb-Screws 31. This cam-plate may of course be made in one or more pieces, as preferred. In the present instance I have shown the cam-plate as made in two pieces, the ends of which are in Contact when in place, so as to make the edge, which is the operative portion, continuous. This edge is lowest at the ends, highest at the sides, and inclined at the quarters, the curvature from end to end corresponding substantially with the curvature of the brim-plate and the cam-track-de., the curvature of an ordinary hat-brim.y The conliguration of the edge of the cam-plate as seen in plan determines the line of movement of the cutter in making the trimming cut, as will be more fully explained. The cam-plate holder is rigidly secured to the standard in any suitable manner. 1 In the IOO present instance I have shown the standard as provided with an angular portion 32,which engages a corresponding opening in the camplate holder, the latter resting on a shoulder on the standard and being held in place by a nut 33.

34 denotes the cutter, which is carried by a vertically-swinging arm 35,which also carries an adjustable guard 36, and is pivoted to a cutter-slide 37. The guard is shown as adjustably secured to the cutter-slide by means of a thumb-screw 38, which passes through a slot 39 in the shank ofthe guide. The cutterslide is adapted to be adjusted in or ont in Ways 40 in an oscillating cutter-plate 4l. The cutter-slide is shown as locked in position in the cutter-plate after adjustment by means of a set-screw 42. The oscillating cutterplate is rigidly secured to an oscillating rod 43, said oscillating rod being free to turn in and being carried by a slide 44, which I have termed the carrying-slide. This slide is adapted to reciprocate in the body 45 of a rotating head K. This rotating head is shown as provided with a socket 46 and the carrying-slide with a shoulder 47. A spring 48, bearing against the bottom of the socket and against the shoulder, acts to move the carrying-slide and the parts carried thereby forward and retain them in operative position, as will be more fully explained.

49 denotes a yoke carrying grooved rollers 50, which are adapted to engage the edge ot" the cam-plate. This yoke is rigidly secured to the oscillating rod,which,as already stated, is pivoted at the inner end of the carryingslide. The oscillating cutter-plate, which is also rigidly secured to the oscillating rod, is in the present instance superposed on a plate 5l, which is really a part of the carryingslide, although in the present instance the only connection between plate 5l and the carrying-slide is the oscillating rod. Plate 5l in the present construction slides in ways 2 in the body. At the rear end of the oscillating cutter-plate is an arc-shaped slot 53. The rear end of the oscillating cutter-plate is retained in place by means of a pin 54,which passes through the slot and lirmly engages plate 5l.

The body 45 of rotating head K is provided with a handle 55 for convenience in operation and is rigidly secured to a cross-plate 56. Upon the under side of the cross-plate are lugs 57, to which yokes 58 are pivoted. These yokes carry rollers 59,which are adapted to travel on cam-track C, as clearly shown in Figs. l and 6.

It will be obvious that when grooved rollers 50, journaled inthe yoke on the carryingslide, travel up the inclines of the cam-plate (corresponding to the quarters oi' a hat-brim) said yoke will be tilted-that is to say, the rollers will lie in a plane at a more or less acute angle to the horizontal plane, one roller being slightly higher than the other. It will be noted in Fig. 5 that carrying-slide v44 is made angular. The socket 46, in which it slides, is of course made to correspond therewith in cross-section. This is in order to cause the entire rotating head to be tilted to correspond with the position of yoke 49, as is clearly shown on Fig. 6, in connection with which see Fig. 3. In order to permit this tilting ol the rotating head, cross-plate 56 is provided with a transversely-elongated opening 60, which receives freely a sleeve 61, which is adapted to slide on the standard. This sleeve is provided with oppositely-extending pins or lugs 62, which lie in longitudinal sockets 63 in the upper side of the crossplate.

64 denotes a spring bearing against the under side of the cam-plate holder and against the sleeve and acting by means of pins 62 upon the crossplate, so that the rollers 59 in yoke 58 are kept closely in engagement with the cam-track, the spring yielding and permitting the cross-plate, and with it the entire rotating head and the parts carried thereby, to rise when rollers 59 travel up the inclines of the cam-track and causing it to move downward again when said rollers travel down the inclines, pins or lugs 62 at the same time permitting the rotating head to tilt fre'ely when yoke 49 on the carrying-slide is tilted by the engagement of rollers 50 with the inclined quarters of the cam-plate.

The operation is briefly as follows: The parts of the machine are all permanent-that is to say, they do not require to be shifted in changing from one style of hat to another, with the exception of the cam plate. In changing from one size of hat to another the operator moves slide-plates 25 in or out, as may be required, by means of screw F. Changes of style will ordinarily not require newsideplates. Usually,therefore,inchanging from one style of hat to another the only change of parts required in the machine is the removal of the cam-plate and the substitution of a new one. This is a very important feature of my invention, as it enables me to make changes in style at a merely nominal expense, it being of course apparent that cam-plates of varying configuration and in one or more pieces can be produced at a relatively tritling expense. In use the operator places the hat-body to be operated upon over the expander and secures it there by oscillation of the hand-lever. The swinging arm is then lowered to place, the guard placed under the edge of the brim, and the cutter passed through the brim, after which the rotating head is swung once around, the entire operation of placing a hat on the machine and trimming the brim being performed in less time than it takes to describe it. The starting position is at one of the ends ot' the brim. In this position the oscillating cutterplate carrying the cutter-slide and cutter lies parallel with the carrying-slide, as is clearly shown in Fig. 2. At the rst quarter, however, as clearly shown in Fig. 3, the oscillating cutter-plate, owing to the position in which yoke 4:9 will be placed by the special portion of the edge of the cam-plate which is at that instant engaged by rollers 50, will be swung forward of the carrying-slide. At the side the oscillating cutter-plate and the carrying-slide will again be parallel, as at the starting-point. At the second quarter the body and. carrying-slide will pass ahead of the oscillating cutter-plate. At the end said parts will be parallel again. At the third quarter said parts will be in the same position as at the irst quarter, which is clearly illustrated in Fig. 3, and at the fourth quarter said parts will again be in thesame position as at the second quarter, this position of the parts not being illustrated in the drawings, owing tothe fact that the principle of operation is made clear in Fig. 3, the relative position of the oscillating cutter-plate and the carrying-slide and other parts of the rotating head being merely a transposition of that illustrated in Fig. 3.

The machine as a whole is simple, durable, and practically impossible to get out of-re pair, an important feature being the relatively inexpensive mode in which the machine is adapted to different styles of hats.

It will of course be understood that my invention is by no means limited to the special details of construction illustrated in the l drawings, but that the details of construction may be greatly varied without departing from the principle thereof.
